As data centers face increasing strain on utility grids, operators are exploring alternative power sources to meet the demands of high-density, AI-driven workloads. This post breaks down six on-site power solutions—from natural gas generators to solar and SMRs—evaluating each option’s cost, reliability, sustainability, and regulatory challenges. Whether you’re planning a new facility or rethinking resiliency, this guide offers a clear snapshot of what’s viable now—and what’s still emerging.

Purkay Labs will attend the 7x24 Exchange Spring 2025 Conference in Orlando from June 8–11 to showcase its latest tools and services for rack-level airflow validation and resiliency testing. With data centers facing rising thermal loads and infrastructure stress, Purkay Labs is focused on helping operators assess real-world cooling performance—especially during failure scenarios. The company will highlight updates to its AUDIT-BUDDY platform and expanded onsite testing services that identify airflow inefficiencies and unlock stranded cooling capacity without disrupting operations.

As high-density IT deployments increase, many legacy data centers are struggling to keep pace—not because of space or IT limitations, but due to cooling constraints. This article examines why simply adding more cooling equipment isn’t always viable, explores the common causes of stranded capacity, and outlines practical strategies to improve thermal efficiency and unlock headroom—without overhauling your infrastructure.

 With the rise of AI and the construction of high-wattage data centers, airflow management has become a critical concern—not just in the white space, but also in supporting infrastructure such as PDU rooms, UPS rooms, and battery rooms. This article highlights the importance of airflow management in these auxiliary spaces and outlines steps to take when overheating conditions arise.

As AI workloads surge, the power—and heat—inside every rack is growing fast. Here’s what that means for your facility, and how to get ahead of the cooling curve.

In our latest article, we break down the four essential Delta-Ts, what they reveal about cooling performance, and why periodic measurement is the only way to ensure your facility is operating as designed. Learn how Delta-T monitoring helps prevent inefficiencies, optimize cooling, and reduce operational costs.

Many legacy data centers need to increase their IT Load but don’t have enough cooling capacity. This article examines a way to free up stranded capacity using the AUDIT-BUDDY system.

Learn how monitoring and improving Server Delta-T can enhance cooling efficiency, reduce energy waste, and prevent equipment failures in data centers.

This article explores how measuring and managing the temperature difference between supply air and server inlets can improve data center cooling efficiency, reduce energy costs, and enhance airflow management.

Learn how managing the temperature difference between server exhaust and CRAC/CRAH return air can enhance cooling efficiency, prevent energy waste, and improve data center airflow management.

This article explores how measuring and optimizing Delta-T across CRAC and CRAH units can improve data center cooling efficiency, reduce energy costs, and enhance airflow management.

In a data center, keeping the equipment cool is crucial to maintaining uptime and efficiency. But how do you know if your cooling system is working as it should? That’s where Delta-T comes in—a simple metric that helps you measure how well your cooling system is performing. In this article, we’ll explain Delta-T, break down the four types, and show you how managing airflow can boost your cooling efficiency.

Here are the ways to use your AUDIT-BUDDY system.

Learn how a data center used Purkay Labs' resiliency testing to assess their cooling system’s ability to maintain operations during failures. The tests provided valuable insights that improved their operational stability and informed strategic upgrades for long-term resilience.

When a cooling system fails in a data center, every second counts. The rise in temperature can quickly lead to overheating, equipment damage, and costly downtime. A swift and calculated response is critical to minimizing these risks. Here’s a step-by-step guide on what actions to take if your cooling systems suddenly stop working.

It’s been 4 years since we released AUDIT-MATE 2.0 - which combined all the features of the Optimize Macro, AUDIT-MATE and WIFI-MATE into ONE program. Check out all the features that have been released from Jan 2020 to November 2024.
